摘要
用微波辐射的方法对锦西炼油厂生产的直馏柴油进行了脱酸精制试验 ,并考察了精制过程中的最佳试验条件。当剂油体积比为 0 .2 5∶1、压力为 0 .0 4MPa、恒压辐射时间为 5min、微波功率为375W、静置时间为 2 0min时 ,可将柴油的酸度由 89.5mgKOH/ 10 0ml降至 3.78mgKOH/ 10 0ml,达到国家规定优质柴油质量标准 (小于 5mgKOH/ 10 0ml) ,且精制过程对柴油性能无影响 ,回收率达到 99.6 %。该精制过程节省时间、耗电量小 ,有利于环境保护。
Putting forward a new kind of method-microwave irradiation in the process of the removal of acid from Jinxi straight-run diesel oil, the optimum conditions of refining process were investigated. The ratio of solvent-to-oil is 0.25∶1, the pressure is 0.04 MPa, the radiant time is 5 min under the constant pressure, microwave power is 375 W. When the resting time is up to 20 min, the acidity will be reduced from 89.5 mgKOH/100mL to 3.78 mgKOH/100mL, and no effect on the quality of the diesel oil, thus it is good enough to meet the best specification of GB. The recovery can reach 99.6%. The whole process of the microwave refinement spends less time, consumes less electricity, and is propitious to the environment.
